A suspension of methyl 2-[3-bromo-4-(3-chloropropoxy)phenyl]-4-methyl-1,3-thiazole-5-carboxylate i91 (0.5 g, 1.24 mmol, 1 eq), 2-methylpyrrolidine (0.3 ml, 3.0 mmol, 2.5 eq), potassium carbonate (0.68 g, 5 mmol, 4 eq) and sodium iodide (20 μg, 0.12 mmol, 0.1 eq) in acetonitrile (10 ml) is stirred overnight at 90° C. The resulting mixture is taken up with dichloromethane, washed with water, dried over magnesium sulfate and concentrated under reduced pressure. The crude product is triturated in diethyl ether to afford 50 mg of methyl 2-{3-bromo-4-[3-(2-methyl-1-pyrrolidinyl)propoxy]phenyl}-4-methyl-1,3-thiazole-5-carboxylate 126.
